We are a web3 bug bounty platform since 2017. We help to set a clear scope (or you can do it by yourself), agree on a budget for valid bugs (platform subscription is free), and make recommendations based on your company`s needs. We launch your program and reach out to our committed crowd of hackers, attracting top talent to your bounty program by with consistent and coordinated attention. Our community of hackers starts searching for vulnerabilities. Vulnerabilities are submitted and managed via our Coordination platform. Reports are reviewed and triaged by the HackenProof team (or by yourself), and then passed on to your security team for fixing. Depending on preference, you can choose to publicly disclose any reports, once the issues are resolved. We connect business with a community of hackers from different parts of the globe.

Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

Submit API test requests via the UI form or invoke EthicalCheck API using cURL/Postman. Request input requires a public-facing OpenAPI Spec URL, an API authentication token valid for at least 10 mins, an active license key, and an email. EthicalCheck engine automatically creates and runs custom security tests for your APIs covering OWASP API Top 10 list Automatically removes false positives from the results, creates a custom developer-friendly report, and emails it to you. According to Gartner, APIs are the most-frequent attack vector. Hackers/bots have exploited API vulnerabilities resulting in major breaches across thousands of organizations. Only see real vulnerabilities; false positives are automatically separated. Generate enterprise-grade penetration test reports. Confidently share it with developers, customers, partners, and compliance teams. Using EthicalCheck is similar to running a private bug-bounty program.
